"One main message from church leaders in recent years is to avoid pornography at all times. Mormons are told to not even see R-rated movies. Mormon language and conversation is chaste, as well as their actions," explained Dr. Mason.

A November 2006 incident was the most shocking for the courtroom.

Arias says Alexander baptized her in his LDS church in a November ceremony. Later that day, she told the jury, he forced himself on her, sexually.

"That time it was painful," Arias said, "I probably would've let him continue, but it became too painful."

"I didn't feel very good about it," Arias later recalled. "I felt like a used piece of toilet paper."

For something like this to happen on the day of one's baptism would be a major problem for Mormons.

"I think that, for Mormons, if it's true, that would be beyond the pale. Baptism is a sacred ordinance. Mormons consider it the gateway on one's pathway to salvation," said Dr. Mason.
